Kenevo rear triangle tolerance

Hey Guys. So now that I've got time for it, I am taking apart my Kenevo and replacing almost everything like wheels, brakes, forks etc.. In order to get new brake hoses in I removed the motor. To remove the motor I needed to disassemble the rear triangle to be able to swing it up and gain access to the rear motor bolts. So I took the rear triangle apart in place of the horst link (yes, in retrospect it might have been easier to just dismount the speed sensor and disconnect the upper link ;). While disassembling the horst link I've noticed that it needs quite some force to take it apart, it even chipped a bit of paint from the eyelet. So while holding the upper and lower part of the rear triangle over each other I've noticed that while the left eyelets are in line, the upper eyelet on the right side is shifted roughly 3mm to the left and 1-2mm up.
On the picture below, you can see how the right eyelets look, when the left side is in line.

So my question now is:
Is that a matter of normal tolerance or should I concern Specialized about that matter?
The bikes hasn't been ridden yet.
It surely is going to be a pain in the a** to reassemble for sure, without the washers falling out...

You didn’t need to remove the motor to do the brakes. Just the motor cover and perhaps the chain stay to frame bolt.
As for tolerances, on my 2019 there was a little bit of misalignment which I am assuming was due to the welding process but my 2020 was spot on. Make sure all the washers are in there correct places as I found mine to have had two washer on one side which cause some alignment issues. Some others on here have had similar issues.

Some better picture though may help diagnose your problem a bit better

Hey Christian, thanks for your input. The washers are where they are supposed to be. I might take some more pictures, but I guess it's hard to really pinpoint the issue, since the angles in a picture of the whole swingarm don't really show much of the issue.

I've taken apart a lot of Horst Link rear triangles and I've never had such an Issue. So I must say I am quite disappointed with the quality of my first Specialized...

Are you sure, I don't need to remove the Motor? I've mounted some TRP brakes and therefore need hoses with the right Banjos. TRP doesn't offer any Banjos to put on an existing line. And I really don't see any way to easily getting any new hoses in, without removing the motor.

Ah I see, I’ve run both stock brake hoses and Hope braided but without barbs. Bit of fishing around but the motor didn’t have to come out.
There isn’t a great deal of room in there so you may be right.

Ah okay, so I suppose it's different for every bike, since there might some tolerance between the frame and the motor cover. On my bike, the hoses run extremely tight between the cover and the frame and I would've had to pull so hard, I'd be afraid to rip something.

So I've removed the motor completely and now I am wondering if the lower part of my frame is bent. The right side of the motor interface seems to be bent inward, while the plastic cover of the motor is straight in that area. Can someone confirm to me if that is normal?
